He dont want camera at his door. Look because they call me after the house is built, there is a construction problem of the column button position. Would be better if they built something lik Π and install the vto at higher position. Now the column button is 1 meter from the ground. If i install the vto and install a camera at his door, the client will see the picture from the ringing doorbell and he must close the vto and open the camera to see the person ringing. So there is no point of 2 vto or 1 vto and 1 camera. The best solution i found is to cancel the column position and use only the door for vto and thats it.
